Co-parental Couples and New Families: A Study of the Primary Triad

2015

Abstract Starting from current areas of research in the field of developmental theories, the aim of this work is to analyse parent-child interactions within a primary triad and to consider co-parenting couple and their children as an interactive matrix. In particular, parent-child relationship could be observed trough new developmental units of observation and coding systems in the multiple scenarios of new families. The deepening of this study may promote an effective connection between research and educational support as well as clinical work with families and parental couples.

Optimization of trigeneration systems by Mathematical Programming: influence of plant scheme and boundary conditions

2014

The large potential for energy saving by cogeneration and trigeneration in the building sector is scarcely exploited due to a number of obstacles in making the investment attractive. The analyst often encounters difficulties in identifying optimal design and operation strategies, since a number of factors, either endogenous (i.e. related with the energy load profiles) and exogenous (i.e. related with external conditions like energy prices and support mechanisms), influence the economic viability. In this paper a decision tool is presented, that simultaneously optimizes the plant lay-out, the sizes of the main components and their operation strategy. For a specific building in the hotel sect…

Assessment of the importance of neutron multiplication for tritium production

2016

Abstract One of the major requirements for a fusion power plant in the future is tritium self-sufficiency. For this reason the scientific community has dedicated a lot of effort to research activity on reactor tritium breeding blankets. In the framework of the international project DEMO, many concepts of breeding blanket have been taken into account and some of them will be tested in the experimental reactor ITER by means of appropriate test blanket modules (TBMs). All the breeding blanket concepts rely on the adoption of binary systems composed of a material acting as neutronic multiplier and another as a breeder. This paper addresses a neutronic feature of these kinds of systems. In parti…

Hydrogen isotopes (δ2H) of polyunsaturated fatty acids track bioconversion by zooplankton

2022

1. Organisms at the base of aquatic food webs synthesize essential nutrients, such as omega-3 polyunsaturated fatty acids (n-3 PUFA), which are transferred to consumers at higher trophic levels. Many consumers, requiring n-3 long-chain (LC) PUFA, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have limited ability to biosynthesize them from the essential dietary precursor α-linolenic acid (ALA) and thus rely on dietary provision of LC-PUFA. 2. We investigated LC-PUFA metabolism in freshwater zooplankton using stable hydrogen isotopes (δ2H) of fatty acids as tracers. We conducted feeding experiments with the freshwater keystone grazer Daphnia to quantify changes in the δ2…

Depressive symptoms and long-term income: The Young Finns Study

2016

Abstract Background Higher depressive symptoms have been associated with lower future income. However, studies examining this issue have had limited follow-up times and have used self-reported measures of income. Also, possible confounders or mediators have not been accounted. Methods 971 women and 738 men were selected from the ongoing prospective Young Finns Study (YFS) that began in 1980. Depressive symptoms were measured in 1992 when participants were from 15 to 30 years old. Information on annual income and earnings from 1993 to 2010 were obtained from the Finnish Longitudinal Employer-Employee Data (FLEED) of Statistics Finland and linked to the YFS. Results Higher depressive symptoms…

Extracellular Vesicles as Shuttles of Tumor Biomarkers and Anti-Tumor Drugs

2014

Extracellular vesicles (EV) include vesicles released by either normal or tumor cells. EV may exceed the nanometric scale (microvesicles), or to be within the nanoscale, also called exosomes. Thus, it appears that only exosomes and larger vesicles may have the size for potential applications in nanomedicine, in either disease diagnosis or therapy. This is of particular interest for research in cancer, also because the vast majority of existing data on EV are coming from pre-clinical and clinical oncology. We know that the microenvironmental features of cancer may favor cell-to-cell paracrine communication through EV, but EV have been purified, characterized, and quantified from plasma of tu…

Neksusanalyysi suomen kielen oppimisesta siivoustyössä

2017

This dissertation focuses on Finnish language learning opportunities in cleaning work, which is the most common job for immigrants in Finland. The study investigates what opportunities and constraints there are for Finnish language learning in cleaning work, how a work community supports language learning, and what factors facilitate or constrain investment in language learning at work. Language learning opportunities are explored from an ecological approach as affordances – the reciprocal relations between an individual and his/her social and physical environment. The study also explores the scaffolding provided by the work community and investment in second language learning. Nexus analys…
